Encrypted P2P sockets over ZeroTier
Home Page: https://zerotier.com

I created a little C program to test embedding zerotier via libzt.
Judging from the output of the callback things seem to work partially. However I can't get the socket layer to work at all.
I tried to set up a mostly copying code from the examples/cpp/ipv6adhoc
. Initially it failed with a segmentation fault. To get around that one I modified src/lwipDriver.cpp
like this:

With this modification my test program starts up, reports IP address added etc. and finally some ZTS_EVENT_PEER_P2P
and ZTS_EVENT_PEER_RELAY
. Among the latter there are some node ids which belong to (Linux) machines running regular zerotier-one (on the same host or another in the same LAN).
However:
zts_connect
fails for:Moreover I wonder: the regular instance does list the libzt based node identifiers (after a while) an keeps a record in peers.d
. But attempts to ping the libzt nodes fail. Is this to be expected?
How would I debug this situation?
Here is the code:

I tried compiling the library to android, C/CPP without a problem, but android part - failes all of times. I already used one week to try to compile the aar file, and it is still failing.
Issues from start
finding all of this, downloading proper sdk and ndk (trying almost every combination) still fails.
Would it be possible to get library we will be able to compile properly on modern java and systems? Please
OSX 10.11.6 El Capitan, amd64, I tried compiling the sdk

For instance: zts_listen() being limited to listening only on a single network.
Hello! I have a very basic proxy server sort of working, but one issue that is proving difficult to figure out is getting the IP address of the virtual socket. This code runs after zts_startjoin() succeeds.
I've never seen zts_has_address() return anything other than a 1.
Like all good bugs, its harder to get it to happen when debugging the code, but the few times it has happened it seems to die at the call to Marhal.PtrToStructure.
Any help is greatly appreciated!
static IPAddress GetAddress(ulong nwid)
{
int err = 0;
IntPtr addressPtr = Marshal.AllocHGlobal(Marshal.SizeOf(typeof(libzt.SockAddrIn)));
int hasAddress = 0;
while((hasAddress = libzt.zts_has_address(nwid)) != 1)
{
Console.WriteLine("No address assigned yet...");
Thread.Sleep(500);
}
if ((err = libzt.zts_get_address(nwid, addressPtr, 2)) < 0)
{
throw new Exception("Failed to get IP address");
}
var address = Marshal.PtrToStructure<libzt.SockAddrIn>(addressPtr);
byte[] ipbytes = BitConverter.GetBytes(address.Addr);
Marshal.FreeHGlobal(addressPtr);
return new IPAddress(ipbytes);
}
Hi, is there a simple config or command-line option which will allow cross-compiling (the entire project) from an x86_64 linux host for an ARM64 linux target? Thanks.
The downloads in the README no longer work; it looks like the entire sdk
directory is gone.
I am building a mesh network using libzt
and wanna give nodes the ability to choose a moon as the gateway to access other networks. I have considered SNAT and DNAT on moons but the application will be unable to know its peers so I want to stick with the route way.
I discover that ZT1Service.hpp
has a zts_get_network_routes
function, and the source code does have functions to synchronize managed routes, but I don't know how it will take effects and whether they will work if I modify the routes later.
Would you mind giving me some instructions about it? Thanks in advance.
Hi again!
I tried running an http service in a Network Container (docker). I can ping the container and connect to the port (telnet), but I can't seem to get any http traffic through. Just hangs 😕
Any idea why this might be?
Regards,
Asbjørn
And possibly other useful network/state management features
Hello,I'm using libzt demo on Windows10.I found that if there is no my own moon, the delay of tow devices is so high that I think If there is an operation like "orbit" in Zerotier-cli of Linux,it will have a better performance. And I had read the document for serval times.But I still no found it.If there was ,could you guide me where is it?Thank you!

I fix this error by deleting the related following rule at CMakeLists.txt:518
//the following rule looks like for dll
install (TARGETS ${DYNAMIC_LIB_NAME}

as your know ,the pipe and write api are the linux apis. and the pipe is a simplex ,Ok .now how can I build the libzt for windows ?If can I get the .lib library without modifying any code or modiying less code?
Thank you!
I notice that the top-level Makefile does not seem to deal with Windows. Would be nice to fix this.
So one of the issues with libzt on Windows is that libzt.h
includes the Winsock headers, but the Windows structures for types like fd_set
and sockaddr_in
are incompatible with the lwIP structures. However, libzt just passes the pointer through to lwIP assuming the structure is the same, and this causes things to break in subtle ways.
It means we're currently having to do workarounds like this in order to actually use zts_*
functions:
https://github.com/HiveMP/ztserver/blob/semaphore-broken/forwardzt.cpp#L11-L31
https://github.com/HiveMP/ztserver/blob/semaphore-broken/forwardzt.cpp#L181 (this is a forced cast because the Winsock sockaddr_in6 and the lwIP sockaddr_in6 are colliding)
This impacts functions like zts_select
which use fd_set
and zts_recvfrom
which write the received address back into a sockaddr
pointer.
For example, this is the Windows (Winsock) definition of fd_set:
typedef struct fd_set {
u_int fd_count; /* how many are SET? */
SOCKET fd_array[FD_SETSIZE]; /* an array of SOCKETs */
} fd_set;
And this is the lwIP definition of fd_set:
typedef struct fd_set
{
unsigned char fd_bits [(FD_SETSIZE+7)/8];
} fd_set;
This also impacts macros like FD_ZERO
, FD_SET
and FD_ISSET
which are defined differently as well.
This is the Windows (Winsock) definition of struct sockaddr_in6
(used in zts_recvfrom
):
typedef struct sockaddr_in6 {
ADDRESS_FAMILY sin6_family; // AF_INET6.
USHORT sin6_port; // Transport level port number.
ULONG sin6_flowinfo; // IPv6 flow information.
IN6_ADDR sin6_addr; // IPv6 address.
union {
ULONG sin6_scope_id; // Set of interfaces for a scope.
SCOPE_ID sin6_scope_struct;
};
} SOCKADDR_IN6_LH, *PSOCKADDR_IN6_LH, FAR *LPSOCKADDR_IN6_LH;
Yet this is the lwIP definition of struct sockaddr_in6
:
struct sockaddr_in6 {
u8_t sin6_len; /* length of this structure */
sa_family_t sin6_family; /* AF_INET6 */
in_port_t sin6_port; /* Transport layer port # */
u32_t sin6_flowinfo; /* IPv6 flow information */
struct in6_addr sin6_addr; /* IPv6 address */
u32_t sin6_scope_id; /* Set of interfaces for scope */
};
Even the definition of struct in6_addr
varies in terms of accessing the data between Windows:
typedef struct in6_addr {
union {
UCHAR Byte[16];
USHORT Word[8];
} u;
} IN6_ADDR, *PIN6_ADDR, FAR *LPIN6_ADDR;
and lwIP:
struct ip6_addr {
u32_t addr[4];
};
Anyway, you get the point. The difference in data structures causes everything to misbehave when data is being passed between the libzt APIs (using Winsock) and the underlying lwIP code.
I think the correct fix here is either:
This issue probably doesn't occur on Linux/Mac because the lwIP structures probably match what sys/socket.h
defines.
When integrating the API into other projects, it would be quite nice to be able to integrate them with CMake. Having this project deliver a CMake file, and use of CMake, may solve other challenges that the project has as well (like detecting platforms, compiler options, etc. etc.)
With a GPL license on an SDK, any application using the SDK must also have its source released under the GPL.
Please consider an MIT or BSD license for the SDK -- to allow zerotier to be used by businesses.
We're experiencing an issue with zts_select which results in semaphore exhaustion in lwip, which results in an assertion because the number of semaphores overflows.
Code to reproduce the issue can be found in ztserver on the "semaphore-broken" branch here: https://github.com/HiveMP/ztserver/blob/semaphore-broken/main.cpp#L240-L252
Once running the application, you can replicate it with:
curl -X PUT \
http://localhost:8080/join \
-H 'Cache-Control: no-cache' \
-H 'Content-Type: application/json' \
-H 'Postman-Token: 9350f4c5-4f53-c05d-4c3f-165a31f3f376' \
-d '{
"nwid": "8bd5124fd6206336",
"path": "ztidentity2"
}'
Wait for ztserver to join the network, then run:
curl -X PUT \
http://localhost:8080/forward \
-H 'Cache-Control: no-cache' \
-H 'Content-Type: application/json' \
-H 'Postman-Token: 6080dc26-719e-0199-0fbf-4a64a9014c46' \
-d '{
"localport": 55000
}'
After a little while in the ztserver output, you'll see the following:

WIndows/NET/C#版本的SDK什么时候发布?作为.NET工程师表示很期待。
At first the when make ios_app_framework,it not works,about 20 compile error.
I add #define ZT_SDK and change some code
Now there is no complie errors.
But some Link command error happend.

I have a use case where I want to use the layer 2 stuff directly, without needing the L3/4 stuff (i.e. no IP, TCP, etc.)
I can build this using libzerotiercore, but it seems like it would be nicer if the SDK offered an AF_PACKET style support.
I do not believe it is necessary to support all the Linux options there (e.g. no need for rings in first version, or fanout, or some of the other socket options -- I think only the socket options for managing multicast are really necessary for full functionality, and initially even those could be elided (I don't need them for example).
The details of the AF_PACKET family on Linux are here:
http://man7.org/linux/man-pages/man7/packet.7.html
I think this is an excellent starting point for offering L2 style capabilities to userland.

The first instance joins the network successfully in a few seconds:
$ gcc -s -O2 -W -Wall -Werror -o t1server6 t1server6.c -Ilibzt/include libzt/bin/lib/libzt.a -lpthread -lstdc++
$ /t1server6
: joined
naddr=2
SERVER_IPV6=fd80:????:????:????:????:????:????:????
: listening
If I start another instance, it hangs for more than a minute (zts_join
never succeeds), even after I stop the first instance.
I'm running the two instances in different directories, thus they use a different path, thus they use different cryptographic identities.
Expected behavior: both instances connect successfully in a few seconds, they get different IP addresses, and they are able to talk to each other.
The expected behavior is similar to TCP sockets on 127.0.0.1.

Not sure how one goes about hooking a c library to javascript.
All the projects in my node_modules that use external c libraries use
https://github.com/nodejs/node-gyp
and there's this thing which may or may not help
https://github.com/charto/nbind
I'm going to give it a shot on the weekend and see how far I get.
https://github.com/zerotier/libzt/blob/master/BUILDING.md says to run `make static_lib', but that doesn't work:
make: *** No rule to make target 'static_lib'. Stop.
Could you please update the instructions?
I'd like to use the gcc optimization flag -Os
. Where can I specify it?
I'm trying to use libzt (at this commit: 5ec7d5b) to connect to a TCP port on an IPv4 and IPv6 peer, but the connect never succeeds.
To make sure that it's not a network connectivity issue, I'm able to use zerotier-cli to join the ad-hoc SSH network:
$ zerotier-cli join ff00160016000000
200 join OK
Then connecting works:
$ gcc -s -O2 -W -Wall -Wextra t1nativex.c
$ ./a.out
SSH-2.0-OpenSSH_7.4p1 Debian-10+deb9u3
However, when I'm doing it with libzt, it doesn't work:
$ g++ -s -O2 -W -Wall -Wextra t1x.c -l... -lpthread
$ ./a.out
...

A mismerge broke my earlier fixes, which means that compiling with PICO is now busted -- here's my fix:
Also, the changes now force you to define STACK_PICO=1 to compile, otherwise static_lib has no default stack option.

I'm experiencing IPv6 TCP connection timeouts when connecting shortly after client and server have joined the ZeroTier network Earth. By expectation is that TCP connections succeed right after zerotier-one -q listnetwork

The bug is indicated by the telnet: Unable to connect to remote host: Connection timed out
line. By this time this connection should succeed, because both the client and the server have joined the ZeroTier network Earth with status OK PUBLIC
.
This is also happening if the client is using libzt to connect to the ZeroTier network Earth, and the server has been connected for >10 minutes (see the details in #31 (comment)):
$ ./a.out
error connecting to remote host: -1 Software caused connection abort
error /miniupnpc/version:1:1: error: expected unqualified-id
We are using the ipv4server_udp
demo included in libzt
, and the ZeroTier One installed by curl | bash
. Both of them run inside an Ubuntu 18.04.1 VM, then we ping from the host and notice the performance difference.

I went to build a C# project using the previous C# code that was up here and noticed it's all been removed, was that by accident, or was it removed for a reason? Will the previous code still work with the current library?
My C is super rusty, but this doesn't seem right -
This makes a scratch buffer of length INET_ADDRSTRLEN
to pass to InetAddress::toString
:
Line 273 in 4f6908b
INET_ADDRSTRLEN
is 16, since an IPv4 address can be at most 15 characters.
But toString
also adds the "port" - which I think is the CIDR mask of the ZT network - onto the end of the string, which means it can be 3 bytes longer, e.g. "/24":
https://github.com/zerotier/ZeroTierOne/blob/ee4783e3fb975d73aabeaa433c346aea043908a9/node/InetAddress.cpp#L132
Unless I'm missing something, that'd be writing 18 bytes into a 16 byte buffer :(
Thanks for the library :)
There is a folder with a readme in /examples/python, yet there is no code example given.
So given the current code found in the DemoServer, it all works great if I am using netcat from a few different windows and even devices, typing in messages manually. Everything seems rather stable and it properly handles clients joining and leaving.
So as a sort of stress test I downloaded a book from Project Gutenberg in text format, and sent the whole file over. Sadly at some point it ends up crashing with a System.ExecutionEngineException.
I edited the book down so it was an even 100k, and it crashes in the exact same spot every time on the 5th send...and after adding a received data counter, its crashing at the exact same # of bytes received - 485320.
That seems awfully weird. Again, any ideas for debugging this would be greatly appreciated!
I never receive any events other than ZTS_EVENT_STACK_UP and ZTS_EVENT_STACK_DOWN. I have tried from homebrew build and building it from source but nothing ever comes through. Am I missing something?
Hey there again. I have created a start of my own libzt interop sample here:
https://github.com/bbatchelder/libzt-interop
Right now it demos how to write a simple single-threaded server. I'd love any feedback you have in general. I have not done socket programming in quite a while. Next up is a multi-threaded example.
Anyways, my understanding is that without setting O_NONBLOCK on the main listening socket, there is a potential race condition where a client connects but drops before the accept() runs.
You can see around line 64 I try calling zts_fcntl() to set O_NONBLOCK, but it fails.
https://github.com/bbatchelder/libzt-interop/blob/master/libzt.Interop.DemoServer/Program.cs#L64
I am getting the value 0 for F_SETFL and 0 for O_NONBLOCK from the libzt.h header (line 475). It seems those are being defined there and overriding what would be the normal lwip values.
https://github.com/zerotier/libzt/blob/master/include/libzt.h#L475
I also see in libzt.cpp you're doing some translation of flags anyways...and I can't say I quite understand the logic there...its either going to be 0 or on Apple or Linux maybe a 1.
https://github.com/zerotier/libzt/blob/master/src/libzt.cpp#L155
Anyways, any help would be greatly appreciated!
Lack of support for select/epoll-like call in the API makes it really hard to use for non-trivial usages.
Do you plan on adding a pure Java integration? Java is already in use with with Android and ZeroTierSynology... I haven't looked at the latter, but %-wise it's a substantial amount of Java code.
Ideally, I'd like a Clojure library. I guess that's too far-fetched to ask for at this point in time...

My application calling libzt
keeps growing its memory usage, and here is the output of top -l 1
on macOS using the UDP server example:

EDIT:

and by looking into the traces, I want to know when and where will lwIP.cpp#L321 be deallocated.I'm hoping to one day do the following inside my projects:
pip3.6 install zerotier
Followed by...
import zerotier
import socket
zerotier.setup(...)
sock = zerotier.socket(socket.AF_INET, socket.SOCK_STREAM)
Or maybe something like this...
import zerotier
zerotier.setup(...)
zerotier.patch_socket_imports()
import requests
req = requests.get('http://10.10.10.10/somewhere/on/my/zt/network')
I also wouldn't mind having some examples as mentioned in #20.
It seems that sometimes lwIP will report that there are too many files open on the system ENFILE
, but this seems to be only from lwIP's connection allocator and not a system-wide issue.
I suspect a maximum number of descriptors is being issued to a lwIP netconn
and they aren't being freed properly by free_socket()
.
The Readme currently points to:
https://download.zerotier.com/RELEASES/1.2.12/dist/libzt/win/libzt-1.2.0r1-win10-x64-release.dll
All other links work fine.
